From this he made the correct deduction that these dark areas were shadows cast by craters and mountains. (b) Calculate the probability that the particle can be found on the interval 0xL0 \leq x \leq L0xL. Others had done the same; what set Galileo apart was that he quickly figured out how to improve the instrument, taught himself the art of lens grinding, and produced increasingly powerful telescopes. The craters and mountains on the Moon : The Moon's surface was not smooth and wonderful as gotten intelligence had guaranteed however unpleasant, with mountains and holes whose shadows changed with the place o . His discovery challenged common beliefs of his time about the bodies of our solar system. The last piece of the puzzle that was missing in our Solar System. Galileo didn't invent the telescope but he did adapt the design of the spyglass for astronomical purposes. The manuscript tract De motu (On Motion), finished during this period, shows that Galileo was abandoning Aristotelian notions about motion and was instead taking an Archimedean approach to the problem. Through refining the design of the telescope he developed an instrument that could magnify eight times, and eventually thirty times. . The story of Galileo and the telescope is a powerful example of the key role that technologies play in enabling advances in scientific knowledge. With further careful observation and calculation he proved that they revolved around Jupiter. Chinese astronomers have long observed sunspots, going back to at least 165 BC. The term retrograde motion for a planet refers to the temporary reversal of the planet's normal west-to-east motion past the background stars as seen from the Earth. is also known as What key event allowed Kepler to develop his own model for solar system motion?

No one seems to know what drew Galileo to astronomy in the first place, and while he made a number of inventions (including an early thermometer and a water pump) its not true to say he invented the telescope. Galileo pioneered the use of the telescope for observing the night sky. At his father's behest, Gailieo gave up his. He had discovered sunspots. Back in 1610, all of this lay in the future and Galileo was still discovering the solar system.

Johannes Kepler wrote a letter of support the following month while additional observations by other astronomers confirmed Galileos claims. Against Scheiner, who, in an effort to save the perfection of the Sun, argued that sunspots are satellites of the Sun, Galileo argued that the spots are on or near the Suns surface, and he bolstered his argument with a series of detailed engravings of his observations.
